Influence of age and BSA in tissue Doppler imaging velocities.
Sir, T Doppler imaging (TDI) is sensitive in detecting early myocardial dysfunction. There are, however, great variations in normal values observed by different workers. This could be because of impact of demographic variables on TDI velocities. We studied 64 normal persons with clinic BP of 120/80mmhg or less and devoid of other cardiovascular risk factors. Mmode, 2-D, pulsed Doppler and tissu...
متن کاملReference values for pulse wave Doppler and tissue Doppler imaging in pediatric echocardiography.
BACKGROUND In pediatric echocardiography, pulse wave Doppler, and tissue Doppler imaging velocities are widely used to assess cardiac function. Current reference values and Z scores, allowing adjustment for growth are limited by inconsistent methodologies and small sample size. Using a standardized approach for parametric modeling and Z score quality assessment, we propose new pediatric referen...
متن کاملDoppler tissue imaging assessment of myocardial velocities and atrioventricular time intervals in term newborn infants during the neonatal period.
BACKGROUND In both term and premature neonates, changes in the systolic and diastolic function of the left ventricle (LV) and right ventricle (RV) reflect the degree of neonatal myocardial immaturity and the co-existence of foetal circulation as well as the presence of concurrent diseases. AIM To evaluate the changes in values of systolic and diastolic LV and RV function using pulse tissue Do...

متن کاملTissue Doppler Imaging versus Conventional Echocardiography in Evaluation of Cardiac Functions in Diabetes Mellitus
Background: Conventional echocardiography and tissue Doppler imaging have been highlighted to diagnose diastolic and systolic heart dysfunction. We aimed to compare tissue Doppler imaging with conventional echocardiography to diagnose heart dysfunctions in diabetes mellitus type 1 (DMT1) patients. <s...
